My Step-Father started out his Navy service as a rear turret gunner on TBF Avenger torpedo/bombers in WWII.  He then went on to become a hardhat salvage diver and eventually an EOD frogman.

He used to tell a story about how the EOD guys, in Vietnam, would have grenades disarmed, than chromed and sold as souvenirs.  Unfortunately, for the unsuspecting buyer, their nice shiny chromed grenade was considered contraband and was seized before the individual jumped on a plane for destinations unknown.

Guess who they called to collect and remove those possible devices of destruction... ;D
